APPARATUS FOR STROPPING RAZOR-BLADESL Specification of Letters Patent.

Patented Sept; 18, 1917.

Application iled .Tune 2, 1916. Serial No. 101,292.

To all whom z't may concern.'

Be it known that I, JOHN MEsNY TOUR- TEL, a citizen of the United Kingdom of Great Britain and Ireland, and residing at Ealing, London, England, have invented a new and useful Apparatus for Stropping Razor-Blades; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improvements in apparatus for stropping razor-blades, and has for its object to provide an apparatus which bystropping both sides of the blade simultaneously, will not bend the cutting edgeV first to one side and then to the other leaving the cuttin .edge in the condition to which it was last nt.

Another object is to provide an even yielding distributed pressure on both sides of the blade, such pressure gradually increasing to a maximum at the extreme edge of the blade, the stropping members. being so yielding that no special'adjustment of the blades to the stropping members is required in order to cause the stropping faces to move tangentia ly of the cutting edge.

Anoth r object is to provide an apparatus which will strop both sides of the bladel Simultaneously, from which the blade may be withdrawn without opening the apparatus, and which may be adopted for various styles of ordinary and safety razor-blades.

Referring to the accompanying drawings, Figure l is a plan view of a device for stropping an ordinary razor-blade parts of the device being removed; Fig. 2 is a like view, showing the razor in position for stropping; Fig. 3 illustrates a section through the line X-Y of Fig. l; Fig. 4 is a sectional view partly in elevation taken near one end of the device; Fig. 5 is an elevation of the op-l erating end thereof; Fig. 6 is a front end l elevation of a form of device for stropping safety razor-blades; Fig. 7 is a side elevation of a device of Fig. 6; Fig. 8 is a sectional end elevation, especially showing the means for clamping a safety razor-blade in place; Figs. 9 and 10 show two forms of safety razor-blades in eneral use; Fi 11 shows a form of plat orm to hold elther form of blade as in Fig. '8.

Similar letters referto similar parts throughout the several views.

Pillars B, B, B are fixed to a plate A and secured to a parallel plateA by nuts C, C, C. A plate D is bent around a portion of the periphery of the plates A, A and around the pillars B, B. The two spindles E, E fpivoted in the plates A, A are connected by gearing wheels F, F and can be rotated by the handle G mounted on the outer extremity of the spindle E, the direction of rotation being controlled by a spring pawlH pivoted on the pillar B.

Cylindrical elastic cushions J Aeach preferably of rubber, inclosed in a loop K, of leather or the like, are'firmly held each to a spindle by a semicylindrical plate L secured by screws M.

The apparatus shown in Figs. 1 to 5 is provided with an opening N in the plate A for the admission of the ordinary razor P which is supported b two rods Q, Q. The extremity of the backl of the razor P is arranged to pass beneath a curved plate R the ends of which engage beneath the pillars B, B, and by this means the razor is held in position. The plate R may be in the form of a thin -flat spring bent into the position shown in dotted lines on Fig. 3 when no blade is inserted and shown engaging the 'razor P in Fig. 4 its function being to accommodate razors of different sectional form. An abutment stop S prevents the razor from being pushed in too far. In the apparatus shown in Figs. 6, 7 and 8,. the opening N rods Q, Q and plate R are dispensed with; and a platform T (a form of which is shown in Fig. 11) is provided, havlng projecting ends T arranged to engage corresponding slots in the plates A, A', pins T2 for the reception of the form of razor blade Z shown in Fig. 9 and pins Ts on the reverse side for the blade shown in Fig. l0.

A holding device for the razor blade in the form of a bent wire V is pivoted to the plates A, A at V and is turned upward in to the position shown in dotted lines in Fig. 6, while the blade is being placed on or removed from the platform T. When the said holding device V is turned down into the position shown in Figs. 7 and 8, it prevents the blade from being ejected from the platform T during operation. I

Figs. 6, 7 and 8 show theplatform arranged for the reception of the blade Z, but upon releasing thenuts C, C, C,-the said platform may be removed and reversed for the reception of the blade Z.

I n both types ofv apparatus above descrlbed the operation and the efects produced areJ similar. Upon rotating the handle Gr in the direction of the arrows shown on the different figures, the two cushions simultaneously approach and then press with gradually increasing force upon the two Sides of the blade the two cushions being squeezed together between the spindles E, E, thus forcing the leather K against the razor edge in the manner shown in Figs. 4 and'8. In each case the razor is preferably allowed a small but sufficient amount of free lateral movementso as to enable the blade to take'up a position in which the pressure becomes equal on the two sides of the blade.

With'the apparatus above described the razor can be subjected to any desired stropping pressure without bending the edge of the blade, such pressure being determined by the relation of the size of cushion em-l ployed to the distance between the spindles E, E, it being obvious that the smaller cushions will' pass each other more freely than larger ones.

Any suitable known means may be used for securing removably or otherwise the apparatus to a table or the like.

Figs. 3, 6 and 7 show la bent plate W fixed to the cover plate D and arranged to slide in a fitting W which is secured to the table. This device, however, forms no part of this invention and is only given as an eX- ample to illustrate the positions in which each apparatus is secured.

What I claim is l. A razor stropping device including a frame, connecting rods extending between the ends thereof, a pair of adjacently positioned razor-blade holding members carried thereby, an arched resilient plate having its ends positioned beneath the connecting rods with the intermediate portion overlying the razor holding members for engagement with the back edge of a razoi blade for holding the same in position on the members, and a pair of rotatable blade stroppers journaled in said frame beneath said members.

2. A-.razor stropping device including a frame, a razor blade holder carried thereby, a pair of rotatable shafts journaled in the frame, a yielding stropper flexibly connected to each shaft, the stroppers being normally cylindrical in cross section and intergeared simultaneously to strike the opposite sides of the razor supported by said holder, the cross sectional shape of said stropping members changing during operative engagement with the razor blade to present a relatively long abrading surface to each side of the blade.

In testimony lwhereof, I have signed my name to this specification in the presence of two subscribing Witnesses. v
